WhatsApp introduces new security measure preventing login via old system devices

WhatsApp, owned by Meta, announced the rollout of a new security measure that prevents users from logging into the app if their devices are running outdated operating systems, affecting both Android and iOS. Users are directed to take the necessary steps to update their devices and continue using the application. According to WABetaInfo, a website specializing in tracking WhatsApp updates, the measure is enforced server-side and does not require installing a new version of the app; instead, it directs users to their device settings to install the latest available operating system update. WhatsApp has not yet specified a list of operating system versions that will be blocked from login. This move is part of efforts to enhance user security, as devices running outdated operating systems may be vulnerable to exploitation due to known security vulnerabilities, potentially allowing attackers to install malware and access stored data. WhatsApp has begun rolling out the feature gradually to specific accounts of Android and iOS users through a server-side update that does not require installing a new version of the app.
